RIBBON MECHANISM FOR'TYPE-W RITERS.

of 'Iichigan, have invented certain new and useful Im rovements in Ribbon Mechanism for T periters," of which the following is a .speci cation. p

This invention relates 'to improvements in .the ribbon mechanism for use with multicolored ribbons on typewriters.

The objects of this invention are to rovide a sim'p'jle and convenient means for a justing the r1 bon so that different portions of the same may be used for the purpose of printing different colors, or the printing with different portions may be to secure printing from different qualities of ribbon as with copying ribbon or a non copying, or record ri on; also to provide a-mechanism that will utilize the full width of ribbon of a single color or quality; and also to. 'rovide a multi-colored ribbon mechanism w b the hand of the operator from the keyboard 2 5 when itis desired to readily shift the same from one color to the other in the progress of Further objects, and ob'ects pertaining to details of construction, wiil definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. 1

The inventionis clearly defined and pointed out in the claims.

A structure embodying'th'e features of my invention is clearly il ustratedin the accompanying drawin forming. apart of this specification, ip-whic Figure lis a detail sideel'evation view of a typewriter'embodying-the features of my improved multi-color mechanism, portions of the frame being broken away and other arts being, shown'in section.'

In the drawing, the sectional views are taken looking in the direction of the little arrows .at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.

The mechanism for shiftiri the ribbon back and forth laterally while it is being fed through the machine is the same as that appearin and described in the atent ap lication o myself and Glenn J. arrett, gerial No. 117,775, filed July 31, 1902. That particular mechanism is not claimed specifically here, but only so much and such parts of the same as'relate to the multic0lored' ribbon feature. I g

The articular features which I seek to patent ere could be made use of in connection with other shifting mechanism than that I have here shown. 7

The ribbon spools O are mounted on sleeves which aremounted on the shafts O.

.The ribbon spools C are adapted to recipro-.

cate and also to be adjusted laterally thereon, being held to rotate with such shafts bysuit able means. An arm X is 'on the shaft 0 and a pin-:0 is carried by the end of the arm X and is arranged parallel with the shaft 0 and extends into t e body of the spool so that the s 001 can reciprocate thereon. This causes t e spool and shaft to revolve together. Each spool is engaged by a. pitman D" which is connected to an arm D on the rock shaft D op osite each spool. The rock shaft D is cause to oscillate bymeans of the slotted lever E embracing a wrist in on theldisk F". The disk F 4 is actuated y the ratchet wheel W, to which it is secured, the same be ing suppo'rted onfa suitable journalF. "A

ratchet awl f is dpivotedto the spacer bar G' and eld yiel ngly in'contact with the ratchet wheel by means of a coiled spring f A 'det'entf engages the wheel FQ The arm D is secured to the end of-the rock shaft D. The arm E is secured to a'collar E which is on the shaft D and is free" tooscillatethereon. The collar E is provided,

'on its endcwith projecting teeth '9', diarhetf rically opposite each other.

Ilro

if, When the teethrest'in theslots i" they while the main writing is black, the collar d is V which are connected to a cross-arm E on the -the other to use either a red and black, or

- vice versa.

such length thatit engages in the peripheral groove H..

When a mu ti-colored ribbon. is inserted, the .cdllar d is. withdrawn and adjusted," so
